FRED C. PARKER, OF TAUNTON, MASSACHUSETTS.

FOOT-RE GISTER.

T o all 'whom it may concern:

Be it known that I, FRED C. PARKER, a citizen of the United States, and a resident of Taunton, in the county of Bristol and Commonwealth of Massachusetts, have invented a new and Im roved Foot-Register, of which the following 1s a full, clear, and exact description.

The invention has for its object to provide a register in the floor of a room that is heated by a system of steam or hot-water heating, by means of which one may warm his feet or any other object he may place thereon, which cannotJ be done with any register now in use with either a system of steam or hot- Water heating.

The invention consists in the novel construction and arrangement of parts, as hereinafter described and claimed.

In the drawings hereto appended, Figure 1. is a top view, of my invention, Fig. 2. is a sectional view thereof on the line f-f in Fig. 1., and F ig. 3. is an end View of my invention.

Reference being made to the drawings, in which similar numbers refer to corres onding parts of all the figures,-1 is a meta box, which depends in an aperture 2 in the floor 3 of a room. The ed e of floor 3 is formed into a recess 4, into W ich fits a flat grating 5, having a border 6 of solid metal, sald border 6 projecting1 beyond the edge of an annular rim 7, whic is formed around the to of the box 1. A second recess 8 is forme below recess 4, in the floor 3, into which fits annular rim 7, the lower surface of rim 7 restin upon the upper surface of recess 8, Whic thus forms a support for the box 1. A mat of asbestos 9 or of other material which is a poor conductor of heat, co-extensive with the top surface 10 of box 1 is laid upon that surface, and a thin sheet of copper or other metal 11, likewise (3o-extensive with the top of box 1, is super-imposed on mat 9 and grating 5 is placed on top of metal sheet 11 so that the top of grating 5 is iush with the top of the iloor 3.

Set in the wall 12 of box 1 are screw-pegs 13 which project above the to surface 10 of box 1 a distance equal to t e combined thickness of mat 9, metal sheet 11, and 1L the thickness of border 6 of gratin 5. In the lower surface of border 6 are fieles 14 registering with the tops 15 of egs 13, which also pass through holes 16 in tfie metal sheet 11 and holes 17 in the mat 9, thus preventing Specification of Letters Patent.

lateral movement, relatively to one another, of box 1 mat 9, metal sheet 11, and grating.

In the bottom wall 18 of box 1, prefera ly near a corner thereof, is an a erture 19, registering with the o en end o a pi e 2U, which is connected wit the boiler of a eater (not shown) and throu h which a fluid heating-medium is intro uced into box 1. On pipe 20 is a shut-off valve 21, operated by a handle 22.

In the center of bottom wall 18 of box 1 is an aperture 23 through which a pipe 24 passes vertically, having its upper end 25a open, inside box 1, and situated a short distance below the upper wall 26 of box 1, and at its lower end, outside the box 1, provided with an air-valve 27, operated by a handle 28. A second pipe 29, the open end of which registers with an aperture 30 in the bottom wall 18 of box 1 at the corner opposite to aperture 19, is employed to convey the heating medium from the box back to the heater (not shown).

When one desires to use my invention, he must open air-valve 28 as well as valve 21 in order to allow the fluid heatin -medium flowing through pipe 20 to entire fill the box 1 and thus come in contact witfi the to Wall 26 of the box; otherwise, the air wil become imprisoned in the up er part of the box and very little heat wil be communicated to the grating 5.

While I have described one form of a paratus which embodies my invention, I o not wish to be understood as limiting myself to this form, but realize that there may be variations thereof, all embodying the principles employed in my invention. For example, when m invention is used on the upper floors of a uilding, it may be found desirable to have the plpes enter through the sides of the box and the air-valves might be laced in the side walls of the box, instead o in the bottom. It may also be found desirable to omit the mat 9, the metal sheet 11, and the grating 5, or anyone of them.

Having now described my invention and its method of operation, what I claim as new and desire to secure by Letters Patent, is,-

In a system of heating for a building emloying a fluid heating medium, the com- Eination of a box seated in an aperture in the Hoor, entirely closing said a erture so as to prevent all passage of air t erethrou h, having one unpartitioned, oblong cham er therein, a layer of heat-resistin material removably placed upon the top o said box, a sheet of metal thereon, and a, grating superim osed over all, the top of the rating bemg su stantially on a level with t e top of the Hoor, means for introducing the heating medium into said chamber, means for conducting said medium from said chamber,

and an outlet valve in the Wall ol said chamber for the purpose of allowing air to escape 10 therefrom, substantially as and for the pur' pose set forth.
